BlockDex sets no cookie of its own. The analytics library sets one.
The analytics identifier
PostHog, the product analytics processor, stores an anonymous identifier in your browser, in a cookie and in local storage, so that two page views in one visit count as one visitor. It holds no name and no email address. BlockDex has no account and no sign-in, so there is nothing to identify you by.
What there is not
There is no sign-in cookie, no advertising cookie, no retargeting pixel and no ad network on the site.
Blocking it
Blocking cookies in your browser blocks it. The index, the search and the install commands work the same without it.
